追溯BALCO电厂2号钢筋混凝土271m高烟囱筒壁现场坍塌的现状,从地基基础、烟囱薄弱部位构造、结构安全度设计、雷击和瞬时阵风效应多方面分析了筒壁坍塌的几种可能性.对BALCO烟囱结构设计的标准和构造要求与中国现行设计标准进行了具体比较.提出了烟囱结构设计的几点启示,供今后国内高烟囱工程设计参考.
Recalling the status quo of the 271m high chimney tube wall collapse in No. 2 reinforced concrete of BALCO Power Plant, several possibilities of tube wall collapse are analyzed from the aspects of foundation foundation, the structure of weak parts of the chimney, structural safety design, lightning stroke and instant gust effect. BALCO chimney structure design standards and construction requirements and the current design standards in China carried out a specific comparison.Construction of the chimney structure of several enlightenment for the future design of high chimney reference.
